To all whom it may concern:

Be it known that 1, JOHN W. Lnnon, a citizen of the United States,residing at'Salina, in the county of Saline and State of Kansas, haveinvented certain new and useful Improvements in Acetylene-Generators, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to improvements in gas generators, and moreparticularly to that class of generators which are adapted to generategas for induction into the cylinders of an internal combustion engine ofan automobile, to assist in starting the same.

An object of this invention is the provision of a generator comprisingtwo sections, one of the sections being adapted to receive carbid, andthe other section receiving liquid which is adapted to be fed to thecarbid, whereby a hot gas is generated which is adapted to flow intocylinders of an engine.

A further object of this invention is the provisionof the generatorconsisting of an upper section and a lower section, the upper sectionbeing composed of two compartments, one to contain water and the otherto contain a liquid composition, and means disposed between the sectionswhereby the liquid contained in the compartments may be fedsimultaneously into the lower compartment in different quantities.

With these and other objects in View, my invention consists in the novelconstructions, combinations, and arrangements of parts to be hereinaftermore fully described, claimed and illustrated in the accompanyingdrawings, in which,

Figure 1, is a side elevation of the upper section of the casing. Fig.2, is an elevation showing the sections connected. Fig. 3, is anelevation of the screen mounted in the lower section. Fig. 4, is a topplan view of the lower section of the casing. Fig. 5 is a longitudinalsection of the lower end of the upper casing and parts carried thereby.

Referring more particularly to the drawings, the numeral 1 designatesthe upper section of the generator casing, and 2, the lower sectionthereof. The lower extremity of the upper section is formed with anoutstanding peripheral flange 3, which is adapted to rest upon the upperedge of the lower section 2, and disposed between the flange 8 and thelower section is the gasket 4 to provide a tight oint therebetween. Thelower section 2 is provided at its upper end with a plurality ofoutstanding ears 5, in which are pivotally mounted the lower ends of thebolts 6, the bolts being adapted to engage in slots 7 formed in theflange 3. Wing nuts 8 are threaded on the upper end of the bolts 6, andare adapted to bear against the upper face of the flange 3, to securelyconnect the sections of the casing together. The upper section 1 isprovided near its lower end with a transverse partition 9, and extendingbe- 7 tween the transverse partition and the upper wall of the sectionis a vertical partition 10, whereby the upper portion of the section isdivided into two compartments. The partition 10 is disposed to one sideof the center of the section thereby forming a small compartment 11which is provided with a suitable filling opening 12, and a largercompartment 13, which is also provided with a filling opening 14. Thepartition 9 is provided with openings 15 and disposed between thepartition 9 and the bottom 16' of the section is a Valve casing 17,which is provided with suitable supports 17 having pipes 18 adapted toengage in the openings 15 in the partition 9. The lower wall 16 is alsoformed with openings arranged in vertical alinement with the openings15, and disposed in the openings are the outlet pipes 19 of the supports17. A suitable valve 20 is arranged in the valve casing, the valve bemgprovided with openings 21 and 22, which are adapted to register with thepipes 18 which in turn register with the openings 15 in the compartments11 and '13 respectively.

The opening 21 is relatively smaller than the opening 22, so that whilethe liquids from the compartments are allowed to flow simultaneouslyinto the lower section, a smaller amount of liquid will flow through theopening 21 than through the opening 22 in the valve. If desired a screen28 may be secured in the lower section near the upper end thereof, toprevent any foreign matter from entering the gas outlet pipe '24, whichis secured in the lower wall 16 of the upper section and extends throughthe side wall thereof, whereby it may be secured to a suitable pipeleading to the intake pipe or manifold of an engine, (not shown).

It will be seen that by the above described construction, the lower Wall16 of the upper section 1 serves as the bottom 0r floor of the aircompartmentbelow the upper liquid containing compartments of saidsections and when the section 1 is placed upon the lower section 2, saidlower wall 16 serves as a cover for said lower section 2. It will alsobe understood that by providing the 5 lower or air compartment in thesection 1, the liquid within the upper compartments will be protectedfrom the eiiects of the hot gases generated in the lower section 2.

The operation of my invention is as fol- 1O lows: In the practical usethereof the lower section of the casing is secured to the frame of anautomobile, and is adapted to contain a quantity of carbid, whereuponthe upper section 1 of the casing may be secured to the lower section bythe fastening bolts or screws 6. The compartment 11 of the up persection is filled with a combustible liquid composition, and thecompartment 13 thereof is iilledwith water or in cold weather with amixture of water and alcohol to pre vent freezing. The liquidcomposition which 1 preferably use in connection with the generatorconsists of the following ingredients; carbon bi-sulfid, washed sulfuricether, gasolcne, picric acid, and sal-ammoniac mixed in their properproportions. The ether and carbon bi-sulfid form volatile liquid whichvaporizes readily, and at the same time the carbon bi-sulfid disguisesthe odor of ether as well as increases the explosive power of themixture; V1 hen the outlet pipe 2%. is connected to the carbureter ofthe automobile, the device is ready for use, and upon rotating the valve20, the liquid composition and the water will be allowed to flow intothe lower section 2 of the casing. The water mixing with the carbid,generates a hot acetylene gas, the heat from this gas vaporizing theliquid composition, and the compound gas is adapted to flow into thecylin- 'ders of the engine through the outlet pipe 24. It will beunderstood that the hot gaseous fuel in the cylinders will aidmaterially in the starting oi the engine.

WVhile the construction illustrated is the preferred embodiment of myinvention, it will be understood that minor changes in construction maybe resorted to without departing from the spirit thereof, or sacrificing'any of its advantages as determined by the scope of the appendedclaim.

Having thus described my invention what I desire to claim and secure byLetters Patent is:

A device of the character described, comprising a casing, including anupper section having a lower wall and a horizontal partition above andparallel with said lower wall, a vertical partition in said uppersection and dividing same into two compartments of unequal size, a lowersection, the lower wall of the upper section serving as a cover for thesaid lower section and the space between said lower wall and horizontalpartition constituting a valve chamber, the larger compartment of theupper section being designed to contain a liquid to react with carbid inthe lower section and the smaller compartment adapted to contain avolatile liquid, distinct conduits establishing communication betweensaid compartments and the lower section and the conduit between thelarger compartment and the lower section being larger than the otherconduit, and valve mechanism in said valve chamber controlling saidconduits.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses. JOHN "W. LEEOH.
